It’s the sales amount of child ASIN instead of all the variants under one parent ASIN, in addition,

it is the total sales amount of all sellers (including hijackers) who sell the ASIN.

In general, the sales you see will be larger than the sales from seller backend, because the seller can only see their own sales, and can’t see the sales from the ASIN hijackers, unless none other sellers follow the ASIN.

The grey number below the weekly sales refers to the average daily sales = weekly sales /7;
